Iowa River Bridge
Posted February 6, 2009, by Ray Kasal (rams1 [at] iowatelecom [dot] net)

This bridge is located 3.5 miles west of Chelsea. A few years ago someone tried to start a fire on the bridge planking. Local fire dept. put out the fire and it now has a steel plate covering the small burned hole.
